Network Slice Selection via Dynamic Application Profile Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G communication systems, determining the appropriate network slice for applications running on terminal devices is challenging, especially when there are multiple 5G core network slices and applications, as existing methods struggle to dynamically update routing policies and manage the mapping between terminal devices and application providers.
Innovation Solution
The proposed solution involves a terminal device influenced network slice selection method, where a Network Repository Function (NRF) updates application profiles based on changes in applications on terminal devices, generates information indicating these updates, and transmits it to a Policy Control Function (PCF) to generate a route policy for the terminal device, ensuring appropriate network slice selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing methods are used for network slice selection, then the basic routing can be maintained, but the system cannot dynamically update routing policies when applications change
Solution Approach 1:
The system implements a feedback mechanism where the NRF receives application change notifications from the terminal device, updates the application profile accordingly, and triggers PCF to regenerate routing policies. This closed-loop feedback ensures routing policies are continuously accurate reflecting current application states, resolving the contradiction between basic routing maintenance and dynamic adaptability.
Solution Approach 2:
The patent introduces dynamic updates to the static routing policy system. The NRF and PCF continuously monitor and respond to application changes, making routing policies dynamic rather than fixed. This allows the system to adapt to changing application requirements while maintaining reliable routing, addressing both dynamic capability and policy accuracy needs.
2Productivity
If manual configuration is used for network slice routing, then routing policies can be controlled, but the process is time-consuming and inefficient
Solution Approach 1:
The system enables self-service automation where the terminal device automatically notifies the NRF of application changes, the NRF automatically updates profiles and triggers policy regeneration in the PCF, and routing policies are automatically applied. This eliminates manual configuration operations, significantly improving productivity while the automated nature reduces operational complexity despite increasing system intelligence.
Solution Approach 2:
The NRF pre-configures application profiles with routing information before actual routing is needed. When application changes occur, the pre-established profile structure allows for rapid updates without requiring complex real-time configuration processes, thus improving generation speed while managing system complexity through pre-prepared templates.
3Measurement precision
If comprehensive application monitoring is implemented, then accurate profile updates can be achieved, but system overhead increases
Solution Approach 1:
The system extracts only the essential application change information needed for routing updates from comprehensive monitoring data. The terminal device sends targeted notifications containing specific application change details to the NRF, which then extracts relevant information for profile updates. This selective extraction achieves accurate detection while minimizing processing overhead by ignoring unnecessary monitoring details.
